Using the technique of TV report, PARIS DERRIERE leads us through an exciting investigation where we explore some of the nooks and crannies of Paris. We discover there the tumultuous passions between men and women for whom sex and the search for depraved pleasures are the main reason to live. Therefore, with the reporter, we surprise: a salesman being paid back in "nature" by a pretty thief / a couple making love in a violent storm / a trio's explosive sexual games / the acrobatics of a man who decides to sodomize his girlfriend in a car / the lustful exploit of a couple in the toilets of a bar and also the libidinous outburst of a gorgeous lady in a hotel.
